First, choose a one set game, play the sea-cup and enter one team or two human players. When it's your turn to serve, move the non-serving player up to the top of the court close to the net. This will force one of the computer players to follow him. Now do a jump serve (push up and fire), then hit the ball to the other computer player by pushing right then down. The ball should drop between him and the net and he should miss the ball. Hopefully this plan should work. I don't know if it works with the other teams like Coco, Freaks etc but it works with the Rollers and the Golden Boys.
